By retrieval, existing utility model patent is as " no-negative pressure water supplier ", it is provided with water tank and no negative pressure device, owing to be provided with no negative pressure device, produce negative pressure in the time of can avoiding water pump to draw water in the water tank, when water tank links to each other with the municipal tap water pipe network, can not influence user's water on every side.The no negative pressure device of avoiding producing negative pressure that such utility model is installed is directly installed on the water tank, can only guarantee that this water tank does not have negative pressure, when this class device is installed in the basement of high building, because the water tank absolute altitude is lower than the tap water pipe network, even the no negative pressure of water tank itself can not guarantee that its water inlet pipe does not produce negative pressure to the tap water pipe network.
Summary of the invention
The purpose of this utility model provides a kind of no-negative pressure water supplier that can not produce negative pressure to the tap water pipe network.No matter this device is installed in any position, and its water tank is linked the tap water pipe network can not produce negative pressure to the tap water pipe network, guarantees user's water is not on every side exerted an influence.
The purpose of this utility model realizes by the following method:
Should " no-negative pressure water supplier " comprise water inlet pipe, water tank, suction water pipe, feed pump, outlet pipe, corresponding valve and suction tracheae and float-ball type automatic air intake and discharge valve.Water inlet pipe enters water tank from water tank top, suction water pipe is drawn by valve by the bottom of water tank and is linked to each other with the water sucking mouth of water pump, the delivery port of water pump is linked the outlet pipe of water pump top by flap valve and valve, architectural feature is: water tank top is provided with a vertical tube and links to each other with float-ball type automatic air intake and discharge valve, and the absolute altitude of the float-ball type automatic air intake and discharge valve on the vertical tube surpasses the absolute altitude of tap water pipe network.
When initially pouring water, the air in the water tank can be by outside the float-ball type automatic air intake and discharge valve drain tank.When water level reached float-ball type automatic air intake and discharge valve, this valve cut out automatically, and the hydraulic pressure in the water tank is equated with the intake pressure of tap water.During water pump operation, in case the pressure of water tank descends, when the water level in the device was lower than float-ball type automatic air intake and discharge valve, the steam vent of automatic air intake and discharge valve was opened, and water tank and atmosphere are linked, and guarantees that water tank can not produce negative pressure.
Because being provided with vertical tube (it highly surpasses the outdoor water inlet pipe network mark of tap water height), water tank links to each other with a float-ball type automatic air intake and discharge valve, even make this device be installed in basement, as long as the head pressure in the water tank is lower than the running water pipe network mark when high, the float-ball type automatic air valve is just opened and is connected atmosphere, can guarantee that this device does not produce negative pressure to the tap water pipe network.Thereby the water tank of this device links the tap water pipe network and neither can exert an influence to user on every side, can utilize the overbottom pressure of tap water to pressurize to the user again, and is energy-conservation very remarkable, also can avoid the secondary pollution of tap water.
